SECTION 1: SPECIFICATION INFORMATION OPERATING CAPACITY (PER HOUR): Model Racks Dishes 300X 1425 300XN 1425 300XLT 1425 OPERATING CYCLE (SECONDS): Wash Time Rinse Time Complete Cycle Time OPERATING TEMPERATURES (°F): Wash Temperature (Minimum) Wash Temperature (Minimum) Rinse Temperature (Minimum) Rinse Temperature (Minimum) WATER REQUIREMENTS: Inlet Temperature (300X/12KW Heater) (Minimum) Inlet Temperature (300X/12KW Heater) (Minimum)
SECTION 1: SPECIFICATION INFORMATION NOTE: Typical Electrical Circuit is based upon (1) 125% of the full amperage load of the machine and (2) typical fixed-trip circuit breaker sizes as listed in the NEC 2002 Edition. Local codes may require more stringent protection than what is dis- played here.
SECTION 1: SPECIFICATION INFORMATION 300X DIMENSIONS LEGEND: A = Drain (1-1/2” NPT) B = Water Inlet (1/2” NPT) C = Electrical Connection NOTE: All dimensions are in inches unless otherwise specified. All vertical dimensions are adjustable by +/- 1/2” (1.3 cm) due to the adjustable bullet feet.

All vertical dimensions are adjustable by +/- 1/2” (1.3 cm) due to the adjustable bullet feet.
UNPACKING THE DISHMACHINE: Once the machine has been removed from the container, ensure that there are no miss- ing parts from the machine. This may not be obvious at first. If it is discovered that an item is missing, contact Jackson imme- diately to have the missing item shipped to you.

SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS INSTALLATION INSTRUCTIONS (CONTINUED) It is also recommended that a shock absorber (not supplied with the models covered in this manual) be installed in the incom- ing water line. This prevents line hammer (hydraulic shock), induced by the solenoid valve as it operates, from causing dam- age to the equipment.

If the water cannot get hot enough, your results may not be satisfactory. This is why Jackson recommends that if you have installed the machine in an area with hard water, that you also install some type of water treatment equipment to help remove the dissolved solids from the water before it gets to the dishmachine.
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS OPERATION INSTRUCTIONS PREPARATION: Before proceeding with the start-up of the unit, verify the following: 1. The pump intake, and wash tank strainers are in place and is clean. 2. The drain stopper is installed. 3. That the wash and rinse arms are screwed securely into place and that their endcaps are tight. The wash and rinse arms should rotate freely.
Page 20
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS SHUTDOWN AND CLEANING: At the end of the workday, close the doors. When the unit completes the cycle, turn the power switch to the OFF position and open the doors. Manually remove the drain stopper from the tub and allow the tub to drain (NOTE: the wash tank water will be hot so caution is advised).
The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However, this does not mean that some items will not wear out in time. Jackson highly recommends that any maintenance and repairs not specifically discussed in this manual should be performed by QUALIFIED SERVICE PERSONNEL ONLY.
WARNING: Inspection, testing and repair of electrical equipment should only be performed by a qualified ser- vice technician. Many of the tests require that the unit have power to it and live electrical components be exposed. USE EXTREME CAUTION WHEN TESTING THE MACHINE. Problem: Dishmachine will not fill after the door is close.

WARNING: Inspection, testing and repair of electrical equipment should only be performed by a qualified ser- vice technician. Many of the tests require that the unit have power to it and live electrical components be exposed. USE EXTREME CAUTION WHEN TESTING THE MACHINE. Problem: Doors will not close completely.
Jackson offers repair kits for replacing some of the wear items associated with solenoid valves which will allow you to save money in that replacement of these parts can take place without removing the solenoid valve from the plumbing assembly.

SECTION 5: SERVICE PROCEDURES RINSE SOLENOID VALVE REPAIR PARTS KIT (CONTINUED) Prying open the coil wire cover 4. When replacing the coil, ensure that when removing the coil wire cover that care is taken not to damage the wires inside. Using the medium flathead screwdriver, gently use it to open the cover enough to where it could be pulled off.

Reconnect the incoming water (if disconnected) and turn on. Then restore power to the unit. Run the unit for at least 10 minutes to ensure there are no leaks. If any problems arise please contact Jackson. SPECIAL PARTS Solenoid Valve Plunger Kit...
Jackson offers repair kits for replacing some of the wear items associated with vacuum breakers which will allow you to save money in that replacement of these parts can take place without removing the vacuum breaker from the plumb- ing assembly.

7. If any of these conditions are present, replace the old plunger with the new one from your kit. Verify that the new plunger is also free from defects. If it is not, contact Jackson immediately. 8. The plunger should drop into the vacuum breaker and seat.
SECTION 5: SERVICE PROCEDURES RINSE REGULATING THERMOSTAT REPLACEMENT Many dishmachines comes with integral booster tanks to ensure proper temperature of the final rinse. Jackson has predominantly used two manufacturers of thermostats, EGO and Stemco. These instructions are for use with kit 06401-003-13-94, which is to replace an EGO rinse regulating thermostat with a Stemco brand.

Always refer to the wiring diagrams on the motor you are installing. If the motor you are installing has had the schematic removed, contact Jackson MSC immediately for techni- cal support.
When servicing plumbing components, take care not to damage the threads of each individual item. Damaged threads can cause leaks and loss of pressure, which could adversely effect the performance of the 300X dishmachine. It is strongly rec- ommended that teflon thread tape, used in conservative amounts, be applied to threads when joining components together. It is not advised to use thread sealing compounds, sometimes referred to as “pipe dope”.
